How to choose stainless steel flange material

　　It is mainly used in food industry and surgical equipment, adding molybdenum to obtain special corrosion-resistant structure. It is also used as "marine steel" because it has better chlorine corrosion resistance than 304. SS316 is commonly used in nuclear fuel recovery units. Grade 18 / 10 stainless steel also generally meets this application level.

　　In order to save stainless steel, welding ring is used. The structure must be machined after welding rings and nozzles. It is generally used for working pressure lower than 2.5MPa. For example, Stainless Forged Steel Socket Welding Flange with smooth surface.

　　The connecting plate of the structure is made of carbon steel or stainless steel. If carbon steel is used, nickel plating is required on the surface. The clamp material is cast aluminum zl7. The sealing roughness of the connecting plate is 20, and there is no obvious radial groove and notch.
